Windows 7: For All my Wireless Networks, There Is A Red X

I'm not a genius at computers but I recently installed Windows 7 on my computer.
I run a wireless connection but when i try to connect through the list of wireless network connections, there is a red X beside all the networks and it says "The capability of your network adapter does not match the requirements of this network."
Can someone please tell me how to fix this?

Love to first you need to fill in your system specs (lower left corner of your posts) so we know what hardware y ou have

then tell us abt your network setup what wifi card, router, etc

thanks

I think my wifi card is TRENDnet TEW-421PC 802.11g.
My router security mode is set to WEP 64 bit (10 hex digits) and my router itself is a D-Link DIR-625
The rest of the specs is in the system specs thingy

1st. Might it be you set up your router to n mode only?
Your card is g TYPE, so router needs to be set to g&n or g only.

2nd, for troubleshooting, set router's security off, and do this also on the computer.
See if without encryption the connection works.

If it does, set router's and computer's security to WPA WPA2 TKIP.

Windows 7 does not support WEP

I turned off the router security and it still didn't work
Any other solutions?

If you turn off router's security, you also have to set security to none on the computer.

How do i do that..

Go to network center.

In the left pane click on "manage wireless networks"

In the next screen, doubleclick on your connection.

In the next dialog, click on security tab

Set security type to "none (open)"

Click ok.

That's it.

windows 7 supports wep just fine.

I dont think WEP is a very secure encryption method IMO.. too easy to crack..WPA 2 is the preferred method
